    Product description

    Dayton Audio raised the bar with the Epique E220CF-8 8" woofer. Constructed of high-end materials like a damped carbon fiber cone, titanium former, and huge neodymium magnet, this driver produces natural sound with remarkably low distortion. In addition, the low moving mass, underhung voice coil, and powerful motor allows the E220CF-8 to deliver incredible dynamics and transient response.

     

    Highlights

    • FEA optimized underhung neodymium motor minimizes distortion, increases efficiency, and improves electrical damping
    • Titanium former provides virtually no eddy currents improving efficiency and transient response
    • Damped carbon fiber cone lowers moving mass and minimizes unwanted resonances
    • Large shorting sleeve lowers inductance and extends frequency response
    • EVS™ (Extensive Venting System) allows generous airflow around the voice coil reducing power compression

     

    Product details

    Dayton Audio Epique E220CF-8 8" Carbon Fiber Cone Neodymium Driver 8 Ohm

     

    The Epique E220CF-8 8" woofer from Dayton Audio combines high-end materials with advanced engineering to create a truly world class, no-compromise driver. Dayton Audio has scrutinized and optimized every aspect of this driver to keep distortion as low as possible while still producing impressive efficiency and a frequency response that is easy to work with. You can expect excellent off-axis and transient response from the E220CF-8 for a great sound stage and realistic sound reproduction. With top-notch components and quality construction, these drivers exemplify the axiom, "The whole is far greater than the sum of its parts."

     

    The Epique E220CF-8 design is all about low distortion and high dynamics. The proprietary FEA optimized motor assembly uses a large neodymium magnet with top and bottom plates thick enough to provide an impressive amount of force across the magnetic gap. The pole piece includes a thick aluminum shorting sleeve that minimizes inductance and provides virtually linear impedance up to 20,000 Hz (under 12 ohms at 20,000 Hz).

     

    Driving the cone is a 2.125" (55 mm) underhung dual layer voice coil wrapped around a titanium former that generates minimal eddy currents improving efficiency and transient response. The focal point of the E220CF-8 is the one-piece epoxy coated carbon fiber cone. Beyond good looks, this cone is extremely light, surprisingly rigid, and provides excellent damping to keep narrow peaks under control, resulting in an incredibly natural yet accurate sound. A rubber surround and large flat spider suspends the cone and keeps it linear through the limits of excursion with minimal restriction, further improving dynamics and transients.

     

    Holding everything together is the open cast aluminum frame, which is rigid but minimalistic enough to allow plenty of "breathing room" for the back side of the cone to keep reflections under control. One other aspect of this driver that deserves attention is the EVS™ (Extensive Venting System) voice coil and motor venting. To keep the voice coil and magnet cool while minimizing compression and extraneous noise the E220CF-8 has 8 vents in the voice coil former, 16 large openings under the spider, 7 peripheral vents in the voice coil gap, and a large aerodynamic dual flared vent through the pole piece.
